Zhichao:
One clarification. What terminal type will be introduced? Xterm, VT400 and Linux?

Thanks

Subject: [edk2-rfc] UEFI terminal console keyboard type extend for Putty

Hi everyone,

Putty is a popular terminal console software in windows and it support various types of terminal keyboard type. I would like to add most of the type support. Here is the key map info. Hope to get comments. Here is the type and mapping table:
Putty function key map:
+=========+======+===========+=============+=============+=============+
| | EFI | | | | |
| | Scan | | | Normal | |
| KEY | Code | VT100+ | Xterm R6 | VT400 | Linux |
+=========+======+===========+=============+=============+=============+
| F1 | 0x0B | ESC O P | NONE | ESC [ 1 1 ~ | ESC [ [ A |
| F2 | 0x0C | ESC O Q | NONE | ESC [ 1 2 ~ | ESC [ [ B |
| F3 | 0x0D | ESC O R | ESC O R | ESC [ 1 3 ~ | ESC [ [ C |
| F4 | 0x0E | ESC O S | ESC O S | ESC [ 1 3 ~ | ESC [ [ D |
| F5 | 0x0F | ESC O T | ESC [ 1 5 ~ | ESC [ 1 5 ~ | ESC [ [ E |

| F7 | 0x11 | ESC [ V | ESC [ 1 8 ~ | ESC [ 1 8 ~ | ESC [ 1 8 ~ |
| F8 | 0x12 | ESC [ W | ESC [ 1 9 ~ | ESC [ 1 9 ~ | ESC [ 1 9 ~ |

| F10 | 0x14 | ESC [ Y | ESC [ 2 1 ~ | ESC [ 2 1 ~ | ESC [ 2 1 ~ |
| Escape | 0x17 | ESC | ESC | ESC | ESC |
| F11 | 0x15 | ESC O Z | ESC [ 2 3 ~ | ESC [ 2 3 ~ | ESC [ 1 3 ~ |
| F12 | 0x16 | ESC O [ | ESC [ 2 4 ~ | ESC [ 2 4 ~ | ESC [ 1 4 ~ |
+=========+======+===========+=============+=============+=============+

For Xterm R6 F1 and F2, it is descripted as ESC+O+P and ESC+O+Q, but it doesn't work on UEFI shell. Same with the SCO mode. So I would ignore the unworkable key map.
